A `common market` (or internal market) is the first important step towards full economic integration and occurs when Member States act freely with all economic resources, not just material goods. This means that all barriers to trade in goods, services, capital and labour will be removed. In addition, non-tariff barriers are reduced and eliminated. For a common market to be successful, it also requires a considerable degree of harmonization of microeconomic policies and common rules for monopoly power and other anti-competitive practices. There may also be common policies for key industries such as the Common Agricultural Policy (CAP) and the European Internal Market (COMMON Fisheries Policy) (COMMON Fisheries Policy( ECF). Free trade zones are created when two or more countries in the same region agree to remove or remove trade barriers for all other members` products. On May 22, 2018, the Council adopted conclusions on how trade agreements are negotiated and concluded. Trade blocs can be autonomous agreements between several states (such as the North American Free Trade Agreement) or be part of a regional organization (such as the European Union). Depending on the degree of economic integration, trading blocs can be considered preferential trade zones, free trade zones, customs union unions, common markets or economic and monetary unions.  The agreement has a strong symbolic impact and shows that nearly four years after Trump launched his “America First” policy of trade agreements with individual countries, Asia continues to engage in multinational nations` efforts for freer trade, seen as a formula for future prosperity. Some proponents of global free trade oppose trade blocs.
Trade blocs are seen by them to promote regional free trade at the expense of global free trade.  Those who work there argue that global free trade is in the interest of each country, as it would create more opportunities to transform local resources into goods and services currently demanded by consumers.  However, scientists and economists continue to discuss whether regional trading blocs are fragmenting the global economy or promoting the expansion of the existing global multilateral trading system.
